Floribunda rose plant named &#39;meidoscope&#39;

ABSTRACT

A new and distinct Floribunda rose plant is provided that forms abundantly and substantially continuously attractive cup-shaped semi-double blossoms that are orange suffused with pink and yellow in coloration. The growth habit is compact and bushy. Vigorous vegetation is formed. Such vegetation is ornamental dark green and bears a glossy aspect on the upper surface. The plant is well suited for providing attractive ornamentation in parks and gardens. The plant can be grown well in containers in view of its compact character, grows well on its own roots, and is well suited for growing in the relatively dry climate of the west coast of the United States. The blossoms commonly are displayed from spring to the time of frost.

BOTANICAL/COMMERCIAL CLASSIFICATION

Rosa hybrida/Floribunda Rose Plant

VARIETAL DENOMINATION

cv. Meidoscope

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida Floribunda rose plant was created by artificial pollination during June 2004 at Le Luc in Provence, France, wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., the seed parent) was the ‘KORfalt’ variety (non-patented in the United States). The ‘KORfalt’ variety is protected in Germany under No. 711,432. The male parent (i.e., the pollen parent) was the ‘MACivy’ variety (U.S. Plant Pat. No. 8,362).

The parentage of the new variety can be summarized as follows:

‘KORfalt’×‘MACivy’.

The seeds resulting from the above pollination were sown and small plants were obtained which were physically and biologically different from each other. Selective study resulted in the identification of a single plant of the new variety.

It was found that the new Floribunda rose plant of the present invention:

-   -   (a) displays a compact and bushy growth habit with vigorous         vegetation,     -   (b) forms abundantly and substantially continuously attractive         cup-shaped semi-double blossoms that are orange suffused with         pink and yellow in coloration,     -   (c) exhibits ornamental dark green foliage with a glossy aspect         on the upper surface, and     -   (d) is well suited for providing attractive ornamentation in         parks and gardens.

The new variety well meets the needs of the horticultural industry and can be grown to advantage in parks and gardens, public areas, and residential landscapes where ornamentation is to be provided. The new plant can be grown well in containers in view of its compact character. The dark green vegetation is vigorous, and strong. Blossoms commonly are displayed from spring to the time of frost. The new plant is particularly well suited for growing in the relatively dry climate on the west coast of the United States, and grows well on its own roots.

The new variety can be readily distinguished from its ancestors. For instance, the ‘KORfalt’ variety bears double flowers of deep gold yellow coloration with significantly heavier petalage (i.e., about 25 to 30 petals), and the ‘MACivy’ variety forms blossoms of a dissimilar apricot coloration also having a greater number of petals.

The new variety of the present invention also readily distinguished from other previously available Floribunda rose varieties, such as the ‘Wekvossutono’ variety (U.S. Plant Pat. No. 18,473). For instance, the blossoms of the ‘Wekvossutono’ variety are very double with about 30 to 45 petals and about 5 and 9 petaloids.

The new variety has been found to undergo asexual propagation at Wasco, Calif., U.S.A., by a number of routes, including budding, grafting, and the use of cuttings. Asexual propagation by the above-mentioned techniques has shown that the characteristics of the new variety are stable and are strictly transmissible by such asexual propagation from one generation to another. Accordingly, the new variety undergoes asexual propagation in a true-to-type manner.

The new variety has been named ‘Meidoscope’ and will be marketed under the POLYNESIAN PUNCH Trademark.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph shows as nearly true as it is reasonably possible to make the same, in a color illustration of this character, typical specimens of buds, blossoms, and foliage of the new variety. The rose plants of the new variety were approximately two years of age and were observed during October 2014 while growing on their own roots outdoors at Wasco, Calif., U.S.A.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart—1995). The description is based on the observation of two-year-old plants during May while growing outdoors on their own roots at West Grove, Pa., U.S.A.
